Although all of the electrical power input to the lighting system is eventually converted to heat, the transport of lighting energy is very complex, particularly for a recessed luminaire, involving all three heat transfer mechanisms--radiation, convection, and conduction--to two spaces, the conditioned space and the ceiling plenum.

Karl Ganser, head of the UIA's Scientific Committee suggested that every building should have a 'deconstruction plan' and that 'everything we build should be gently returned into the cycle of nature', In an early plenum devoted to 'The Built and the Natural', Thomas Herzog, one of Germany's most active and evangelizing eco-architects, looked at lessons drawn from tradition and history, exploring vernacular architecture from Venice, Tunis and the Yemen.

Phase I of the study, conducted in 2003 and 2004, studied the hydrodynamic phenomena of the M-hull as a captured air plenum design, investigated performance prediction methods and evaluated its potential as a future Naval ship concept, with the Stiletto being one variant of the concept.

We agreed to form a working group consisting of representatives of the University, including the Student and Professor Plenums, and the Ministry of Education and Science, which will develop an analysis on the state of affairs in the higher education based on which the concept for drafting a law will be defined," the press release says.

Thus, in sprinkled buildings, if combustible materials (plenum cables are considered combustible because they are not limited combustible) are installed in concealed spaces, such as air-return plenums, then the space must be sprinkled.
